The Model 1120 manual on the website looks nothing like our machine. It also says when ordering parts give model number 159.262

I know how useful the owners manual can be since it carries some good troubleshooting tips. While you are waiting for your expert answer, I suggest you add to the thread of this question and include the full model number of your appliance so that the expert can provide you with a more detailed answer. I did manage to find a link in where you can enter your appliance model number and the owners manual will pop up. I am also adding a second link in where you can order the owners manual for your appliance. I hope my links are useful.
